The construction worker, who is not employed by the airline, was reportedly in cardiac arrest when he was rushed to the hospital. He was pronounced dead at Jamaica Hospital a little more than an hour later.
The accident is under investigation by OSHA.
Officials say the victim was working on Terminal 5, the historic Trans World Airlines terminal at Kennedy Airport currently under renovation by JetBlue.
The $875 million project is constructing a new terminal for the airline's expanding fleet, while simultaneously repairing the 46-year-old TWA Flight Center at Terminal 5, which embodied the ''Come Fly With Me'' era of jet-setting.
The landmark TWA terminal, designed by Eero Saarinen in 1962, could not accommodate modern planes because of its physical and aeronautical limitations.
Queens-based JetBlue began operations in 2000. Terminal 5 ceased operations the following year.
